FIELD OF THE INVENTION

The invention generally relates to the field of insect inhibitory proteins. A novel class of proteins are disclosed exhibiting insect inhibitory activity against agriculturally relevant pests of crop plants and seeds, particularly Lepidopteran species of insects. Plants, plant parts, and seeds, including plant and microbial cells, and vectors containing a recombinant polynucleotide construct encoding one or more of the disclosed toxin proteins are provided.

BACKGROUND OF THE INVENTION

Improving crop yield from agriculturally significant plants including, among others, corn, soybean, sugarcane, rice, wheat, vegetables, and cotton, has become increasingly important. In addition to the growing need for agricultural products to feed, clothe and provide energy for a growing human population, climate-related effects and pressure from the growing population to use land other than for agricultural practices are predicted to reduce the amount of arable land available for farming. These factors have led to grim forecasts of food security, particularly in the absence of major improvements in plant biotechnology and agronomic practices. In light of these pressures, environmentally sustainable improvements in technology, agricultural techniques, and pest management are vital tools to expand crop production on the limited amount of arable land available for farming.

Insects, particularly insects within the order Lepidoptera, are considered a major cause of damage to field crops, thereby decreasing crop yields over infested areas. Lepidopteran pest species which negatively impact agriculture include, but are not limited to, Bean shoot moth (Crocidosema aporema), Black armyworm (Spodoptera cosmioides), Black cutworm (Agrotis ipsilon), Corn earworm (Helicoverpa zea), Cotton leaf worm (Alabama argillacea), Diamondback moth (Plutella xylostella), European corn borer (Ostrinia nubilalis), Fall armyworm (Spodoptera frugiperda) including Cry1Ab, Cry1Ac, and Cry1Fa resistant Fall armyworm, Old World bollworm (OWB, Helicoverpa armigera), Southern armyworm (Spodoptera eridania), Soybean looper (Chrysodeixis includens), Spotted bollworm (Earias vittella), Southwestern corn borer (Diatraea grandiosella), Sugarcane borer (Diatraea saccharalis), Sunflower looper (Rachiplusia nu), Tobacco budworm (Heliothis virescens), Tobacco cutworm (Spodoptera litura, also known as cluster caterpillar), Western bean cutworm (Striacosta albicosta), and Velvet bean caterpillar (Anticarsia gemmatalis).

Historically, the intensive application of synthetic chemical insecticides was relied upon as the pest control agent in agriculture. Concerns about the indiscriminate toxic effects of such insecticides, and concerns for the environment and human health, in addition to emerging resistance issues, stimulated the research and development of biological pesticides. This research effort led to the progressive discovery and use of various entomopathogenic microbial species, including bacteria.

The biological control paradigm shifted when the potential of entomopathogenic bacteria, especially bacteria belonging to the genus Bacillus, was discovered and developed as a biological pest control agent. Strains of the bacterium Bacillus thuringiensis (Bt) have been used as a source for pesticidal proteins since the dawn of molecular biology, and it was discovered that certain Bt strains exhibit a high level of toxicity against specific insects. Bt strains are known to produce delta-endotoxins that are localized within parasporal crystalline inclusion bodies at the onset of sporulation and during the stationary growth phase (e.g., Cry proteins), and are also known to produce secreted insecticidal proteins. Upon ingestion by a susceptible insect, delta-endotoxins as well as secreted toxins may exert their effects at the surface of the midgut epithelium, disrupting the cell membrane, leading to cell disruption and death. Genes encoding insecticidal proteins have also been identified in bacterial species other than Bt, including other Bacillus and a diversity of additional bacterial species, such as Pseudomonas, Serratia, Xenorhabdus, and Photorhabdus species, as well as other bacilli including but not limited to Brevibacillus laterosporus, Lysinibacillus sphaericus (“Ls” formerly known as Bacillus sphaericus), Paenibacillus popilliae and Paenibacillus lentimorbus. In addition, insecticidal toxins have also been identified from a variety of non-bacterial sources including ferns and other plant related species, and arachnid venoms, and the delivery of dsRNA in the diet of some pest species has been identified as an effective pest management strategy.

Crystalline and secreted soluble insecticidal toxins that are preferred for the purposes of the present invention are highly specific for the target pest species and have gained worldwide acceptance as alternatives to chemical insecticides. For example, insecticidal toxin proteins have been employed in various agricultural applications to protect agriculturally important plants from insect infestations, decrease the need for chemical pesticide applications, and increase yields. Insecticidal toxin proteins may be used to control agriculturally-relevant pests of crop plants by mechanical methods, such as spraying to disperse microbial formulations containing various bacteria strains onto plant surfaces, or alternatively by using genetic transformation techniques to produce transgenic plants and seeds expressing insecticidal toxin protein.

The use of transgenic plants expressing insecticidal toxin proteins has been globally adopted. For example, in 2016, 23.1 million hectares were planted with transgenic crops expressing Bt toxins and 75.4 million hectares were planted with transgenic crops expressing Bt toxins stacked with herbicide tolerance traits (ISAAA. 2016. Global Status of Commercialized Biotech/GM Crops: 2016. ISAAA Brief No. 52. ISAAA: Ithaca, N.Y.). The global use of transgenic insect-protected crops and the limited number of insecticidal toxin proteins used in these crops has created a selection pressure for existing insect alleles that impart resistance to the currently-utilized insecticidal proteins.

The development of resistance in target pests to insecticidal toxin proteins creates the continuing need for discovery and development of new insecticidal toxin proteins that are useful for managing the pest populations, including those with resistance alleles. New protein toxins with management efficacy and which exhibit control over a broader spectrum of susceptible insect species will reduce the number of surviving insects which can develop resistance alleles. In addition, the use in one plant of two or more transgenic insecticidal toxin proteins toxic to the same insect pest and displaying different modes of action, or alternatively two or more different modes of toxic action (for example, a transgene encoding a dsRNA targeting an essential gene for suppression coupled with a transgene that encodes a peptide or protein toxin, both toxic to the same insect species), reduces the probability of resistance in any single target insect species. Additionally, use of self-limiting technologies such as those provided by Oxitec Ltd, when used together with the proteins of the present invention, could improve durability of the traits imparted to transgenic crops expressing proteins of the present invention (Zhou et al. 2018. Combining the high-dose/refuge strategy and self-limiting transgenic insects in resistance management—a test in experimental mesocosms. Evol Appl 11(5):727-738; Alphey et al. 2009. Combining pest control and resistance management: synergy of engineered insects with Bt crops. Journal of Economic Entomology, 102: 717-732).

Thus, the inventors disclose herein a novel protein from Bacillus thuringiensis, and exemplary recombinant proteins, that each exhibit insecticidal activity against target Lepidopteran species, particularly against Black armyworm (Spodoptera cosmioides), Black cutworm (Agrotis ipsilon), Corn earworm (Helicoverpa zea), European corn borer (Ostrinia nubilalis), Fall armyworm (Spodoptera frugiperda), South American podworm (Helicoverpa gelotopoeon), Southern armyworm (Spodoptera eridania), Soybean looper (Chrysodeixis includens), Southwestern corn borer (Diatraea grandiosella), Sugarcane borer (Diatraea saccharalis), Sunflower looper (Rachiplusia nu), Tobacco budworm (Heliothis virescens), and Velvet bean caterpillar (Anticarsia gemmatalis).

DETAILED DESCRIPTION OF THE INVENTION

One problem in the art of agricultural pest control can be characterized as a need for new toxin proteins that are efficacious against target pests, exhibit broad spectrum toxicity against target pest species, are capable of being expressed in plants without causing undesirable agronomic issues, and provide an alternative mode of action compared to current toxins that are used commercially in plants.

Novel pesticidal proteins exemplified by TIC4029 and amino acid sequence variants are disclosed herein and address each of these problems in the art, particularly against a broad spectrum of Lepidopteran insect pests, and more particularly against Bean shoot moth (Crocidosema aporema), Black armyworm (Spodoptera cosmioides), Black cutworm (Agrotis ipsilon), Corn earworm (Helicoverpa zea), European corn borer (Ostrinia nubilalis), Fall armyworm (Spodoptera frugiperda), South American podworm (Helicoverpa gelotopoeon), Southern armyworm (Spodoptera eridania), Soybean looper (Chrysodeixis includens), Southwestern corn borer (Diatraea grandiosella), Sugarcane borer (Diatraea saccharalis), Sunflower looper (Rachiplusia nu), Tobacco budworm (Heliothis virescens), and Velvet bean caterpillar (Anticarsia gemmatalis).

Reference in this application to TIC4029, “TIC4029 protein”, “TIC4029 protein toxin”, “TIC4029 pesticidal protein”, “TIC4029-related toxins”, “TIC4029-related toxins”, “TIC4029 class”, “TIC4029 protein toxin class”, “TIC4029 toxin protein class”, and the like, refer to any novel pesticidal protein or insect inhibitory protein, that comprises, that consists of, that is substantially homologous to, that is similar to, or that is derived from any pesticidal protein or insect inhibitory protein sequence of TIC4029 (SEQ ID NO:2), and the truncation toxin proteins, TIC4029_1 (SEQ ID NO:4) and TIC4029_8 (SEQ ID NO:10) and pesticidal or insect inhibitory segments thereof, or combinations thereof, that confer activity against Lepidopteran pests, including any protein exhibiting pesticidal or insect inhibitory activity if alignment of such protein with TIC4029 results in an amino acid sequence of identity of any fraction percentage from about 86% to about 100% percent. The TIC4029 proteins include both the plastid-targeted and non-plastid targeted form of the proteins.

The term “segment” or “fragment” is used in this application to describe consecutive amino acid or nucleic acid sequences that are shorter than the complete amino acid or nucleic acid sequence describing TIC4029 or TIC4029 truncation variant proteins. A segment or fragment exhibiting insect inhibitory activity is also disclosed in this application if alignment of such segment or fragment, with the corresponding section of the TIC4029 protein set forth in SEQ ID NO:2, the TIC4029_1 protein set forth in SEQ ID NO:4, or the TIC4029_8 protein set forth in SEQ ID NO:10, results in amino acid sequence identity of any fraction percentage from about 87 to about 100 percent between the segment or fragment and the corresponding segment of amino acids within the TIC4029 or TIC4029 truncation variant proteins. A fragment as described herein may comprise at least 50, at least 100, at least 250, at least 500, at least 600, at least 800, or at least 1000 contiguous amino acids of SEQ ID NO: 2, 4, or 10. A fragment as described herein may have the pesticidal activity of any of SEQ ID NO: 2, 4, or 10.

Reference in this application to the terms “active” or “activity”, “pesticidal activity” or “pesticidal” or “insecticidal activity”, “insect inhibitory”, “pesticidally effective”, or “insecticidal” refer to efficacy of a toxic agent, such as a protein toxin, in inhibiting (inhibiting growth, feeding, fecundity, or viability), suppressing (suppressing growth, feeding, fecundity, or viability), controlling (controlling the pest infestation, controlling the pest feeding activities on a particular crop containing an effective amount of the TIC4029, or TIC4029 truncation variant proteins or killing (causing the morbidity, mortality, or reduced fecundity of) a pest. These terms are intended to include the result of providing a pesticidally effective amount of a toxic protein to a pest where the exposure of the pest to the toxic protein results in morbidity, mortality, reduced fecundity, or stunting. These terms also include repulsion of the pest from the plant, a tissue of the plant, a plant part, seed, plant cells, or from the particular geographic location where the plant may be growing, as a result of providing a pesticidally effective amount of the toxic protein in or on the plant. In general, pesticidal activity refers to the ability of a toxic protein to be effective in inhibiting the growth, development, viability, feeding behavior, mating behavior, fecundity, or any measurable decrease in the adverse effects caused by an insect feeding on this protein, protein fragment, protein segment or polynucleotide of a particular target pest, including but not limited to insects of the order Lepidoptera. The toxic protein can be produced by the plant or can be applied to the plant or to the environment within the location where the plant is located. The terms “bioactivity”, “effective”, “efficacious” or variations thereof are also terms interchangeably utilized in this application to describe the effects of proteins of the present invention on target insect pests.

A pesticidally effective amount of a toxic agent, when provided in the diet of a target pest, exhibits pesticidal activity when the toxic agent contacts the pest. A toxic agent can be a pesticidal protein or one or more chemical agents known in the art. Pesticidal or insecticidal chemical agents and pesticidal or insecticidal protein agents can be used alone or in combinations with each other. Chemical agents include but are not limited to dsRNA molecules targeting specific genes for suppression in a target pest, organochlorides, organophosphates, carbamates, pyrethroids, neonicotinoids, and ryanoids. Pesticidal or insecticidal protein agents include the protein toxins set forth in this application, as well as other proteinaceous toxic agents including those that target Lepidopterans, as well as protein toxins that are used to control other plant pests such as Cry, Vip, and Cyt proteins available in the art for use in controlling Coleopteran, Hemipteran and Homopteran species.

It is intended that reference to a pest, particularly a pest of a crop plant, means insect pests of crop plants, particularly those Lepidoptera insect pests that are controlled by the TIC4029 protein toxin class. However, reference to a pest can also include Coleopteran, Hemipteran and Homopteran insect pests of plants, as well as nematodes and fungi when toxic agents targeting these pests are co-localized or present together with the TIC4029 protein or the TIC4029 truncation variant proteins or a protein that is 87 to about 100 percent identical to TIC4029 protein or the TIC4029 truncation variant proteins. The phrase “present together” or “co-localized” are intended to include any instance of which a target insect pest has been contacted by the TIC4029 protein toxin class as well as any other toxic agent also present in a pesticidally effective amount relative to the target insect pest. “Contacted” is intended to refer to being present in the diet of the target pest, and the diet is consumed by the target pest.

The TIC4029 or the TIC4029 truncation variant proteins are related by a common function and exhibit insecticidal activity towards insect pests from the Lepidoptera insect species, including adults, pupae, larvae, and neonates.

The insects of the order Lepidoptera include, but are not limited to, armyworms, cutworms, loopers, and heliothines in the Family Noctuidae, e.g., Fall armyworm (Spodoptera frugiperda), Bean shoot moth (Crocidosema aporema), Beet armyworm (Spodoptera exigua), Black armyworm (Spodoptera cosmioides), Southern armyworm (Spodoptera eridania), bertha armyworm (Mamestra configurata), black cutworm (Agrotis ipsilon), cabbage looper (Trichoplusia ni), soybean looper (Pseudoplusia includens), Sunflower looper (Rachiplusia nu), velvetbean caterpillar (Anticarsia gemmatalis), green cloverworm (Hypena scabra), tobacco budworm (Heliothis virescens), granulate cutworm (Agrotis subterranea), armyworm (Pseudaletia unipuncta), Sugarcane borer (Diatraea saccharalis), Sunflower looper (Rachiplusia nu), South American podworm (Helicoverpa gelotopoeon) western cutworm (Agrotis orthogonia); borers, casebearers, webworms, coneworms, cabbageworms and skeletonizers from the Family Pyralidae, e.g., European corn borer (Ostrinia nubilalis), navel orange worm (Amyelois transitella), corn root webworm (Crambus caliginosellus), sod webworm (Herpetogramma licarsisalis), sunflower moth (Homoeosoma electellum), lesser cornstalk borer (Elasmopalpus lignosellus); leafrollers, budworms, seed worms, and fruit worms in the Family Tortricidae, e.g., codling moth (Cydia pomonella), grape berry moth (Endopiza viteana), oriental fruit moth (Grapholita molesta), sunflower bud moth (Suleima helianthana); and many other economically important Lepidoptera, e.g., diamondback moth (Plutella xylostella), pink bollworm (Pectinophora gossypiella), and gypsy moth (Lymantria dispar). Other insect pests of order Lepidoptera include, e.g., cotton leaf worm (Alabama argillacea), fruit tree leaf roller (Archips argyrospila), European leafroller (Archips rosana) and other Archips species, (Chilo suppressalis, Asiatic rice borer, or rice stem borer), rice leaf roller (Cnaphalocrocis medinalis), corn root webworm (Crambus caliginosellus), bluegrass webworm (Crambus teterrellus), southwestern corn borer (Diatraea grandiosella), sugarcane borer (Diatraea saccharalis), spiny bollworm (Earias insulana), spotted bollworm (Earias vittella), American bollworm (Helicoverpa armigera), corn earworm (Helicoverpa zea, also known as soybean podworm and cotton bollworm), tobacco budworm (Heliothis virescens), sod webworm (Herpetogramma licarsisalis), Western bean cutworm (Striacosta albicosta), European grape vine moth (Lobesia botrana), citrus leafminer (Phyllocnistis citrella), large white butterfly (Pieris brassicae), small white butterfly (Pieris rapae, also known as imported cabbageworm), beet armyworm (Spodoptera exigua), tobacco cutworm (Spodoptera litura, also known as cluster caterpillar), and tomato leaf miner (Tuta absoluta).

Reference in this application to an “isolated DNA molecule”, or an equivalent term or phrase, is intended to mean that the DNA molecule is one that is present alone or in combination with other compositions, but not within its natural environment. For example, nucleic acid elements such as a coding sequence, intron sequence, untranslated leader sequence, promoter sequence, transcriptional termination sequence, and the like, that are naturally found within the DNA of the genome of an organism are not considered to be “isolated” so long as the element is within the genome of the organism and at the location within the genome in which it is naturally found. However, each of these elements, and subparts of these elements, would be “isolated” within the scope of this disclosure so long as the element is not within the genome of the organism and at the location within the genome in which it is naturally found. Similarly, a nucleotide sequence encoding an insecticidal protein or any naturally occurring insecticidal variant of that protein would be an isolated nucleotide sequence so long as the nucleotide sequence was not within the DNA of the bacterium from which the sequence encoding the protein is naturally found. A synthetic nucleotide sequence encoding the amino acid sequence of the naturally occurring insecticidal protein would be considered to be isolated for the purposes of this disclosure. For the purposes of this disclosure, any transgenic nucleotide sequence, i.e., the nucleotide sequence of the DNA inserted into the genome of the cells of a plant or bacterium, or present in an extrachromosomal vector, would be considered to be an isolated nucleotide sequence whether it is present within the plasmid or similar structure used to transform the cells, within the genome of the plant or bacterium, or present in detectable amounts in tissues, progeny, biological samples or commodity products derived from the plant or bacterium.

Reference in this application to the term “self-limiting gene” refers to one or more genes that limits survival of the host, resulting in a reduction in the host population. Such technology is offered by Oxitech Ltd. Transgenic male insects carrying a transgenic self-limiting gene are released and reproduce with wild females. As a result, the progeny inherit a copy of the self-limiting gene. The self-limiting gene disrupts the proper functioning of the insects' cells by over-producing a protein in them, interfering with the cells' ability to produce other essential proteins needed for development. By disrupting the insect's normal development, the gene prevents it from surviving to adulthood. For example, the self-limiting Diamondback Moth (Plutella xylostella) strain OX4319L was developed by Oxitech Ltd and carries a male-selecting gene that utilizes sequences from the sex determination gene doublesex (dsx). The gene expresses sex-alternate splicing, to engineer female-specific expression of the self-limiting gene which prevents survival of female offspring beyond the larval stage and allows for production of male only cohorts of self-limiting moths. After being released, males mate with pest females, leading to a reduction in the number of female offspring in the next generation, thereby locally suppressing P. xylostella populations. To facilitate the rearing of large numbers of males for release within diamondback moth production facilities, the expression of female-specific dsx within the OX4319L strain is repressed by the addition of tetracycline, or suitable analogs, into the larval feed. OX4319L also expresses the fluorescent protein, DsRed, to permit the effective monitoring of the presence of this strain in the field (Jin et al., 2013. Engineered female-specific lethality for control of pest Lepidoptera. ACS Synthetic Biology, 2: 160-166). This technology, when applied in the field with plants containing the toxin genes of the present invention, can delay or prevent the onset of resistance of pest species targeted for control by the toxin genes and proteins of the present invention, thus giving a greater durability of any plant product containing the toxin genes and proteins of the present invention. This technology could be applied to fall armyworm, corn earworm, corn rootworm, and soybean looper, as well as a host of other crop pest species.

As described further in this application, an open reading frame (ORF) encoding TIC4029 (SEQ ID NO:1) was discovered in DNA obtained from Bacillus thuringiensis strain EGBS0016. The coding sequence was cloned and expressed in microbial host cells to produce recombinant proteins used in bioassays. Bioassay using microbial host cell-derived proteins of TIC4029 demonstrated activity against the Lepidopteran species Black armyworm (BAW, Spodoptera cosmioides), Black cutworm (BCW, Agrotis ipsilon), Corn earworm (CEW, Helicoverpa zea), European corn borer (ECB, Ostrinia nubilalis), Fall armyworm (FAW, Spodoptera frugiperda), Southern armyworm (SAW, Spodoptera eridania), Soybean looper (SBL, Chrysodeixis includens), Southwestern corn borer (SWC, Diatraea grandiosella), Sugarcane borer (SCB, Diatraea saccharalis), Sunflower looper (SFL, Rachiplusia nu), Tobacco budworm (TBW, Heliothis virescens), and Velvet bean caterpillar (VBC, Anticarsia gemmatalis).

TIC4029_1 and TIC4029_8 disclosed herein are two different amino acid sequence deletion variants of TIC4029. TIC4029_1 comprises a deletion of the carboxy-terminal protoxin domain, i.e., amino acids beyond position 603 of the native toxin. TIC4029_1 was expressed in bacteria and assayed against BAW, SAW, and VBC and demonstrated activity against all three Lepidopteran insect pests. TIC4029_8 comprises amino acids 28-607 of the native TIC4029 protein and was made by deleting the N-terminal amino acids 1-27 and the amino acids of the protoxin domain after amino acid 607 of the native protein. In addition, the arginine residue of TIC4029 at amino acid position 27 of the native protein was replaced by a methionine residue. The TIC4029_8 toxin protein represents the tryptic core of the native TIC4029 toxin protein.

FIG. 1 presents an alignment of TIC4029, TIC4029-1, and TIC4029_8 illustrating the truncations of TIC4029_1 and TIC4029_8 relative to TIC4029. Synthetic coding sequences designed for expression of TIC4029 protein class toxins in a plant cell were produced including TIC4029 (SEQ ID NO' s:5-7), TIC4029_1 (SEQ ID NO:8), and TIC4029_8 (SEQ ID NO:9).

Soybean plants expressing the toxins, TIC4029 (encoded by SEQ ID NO:5), TIC4029_1 (encoded by SEQ ID NO:8), and TIC4029_8 (encoded by SEQ ID NO:9) were assayed using leaf discs and demonstrated efficacy against SBL and suppression of SAW. Corn plants expressing TIC4029 (encoded by SEQ ID NO:7) and TIC4029_8 (encoded by SEQ ID NO:9) demonstrated efficacy against SWC, and corn plants expressing TIC4029_1 (encoded by SEQ ID NO:8) demonstrated suppression of SWC. In screenhouse trials in the United States, soybean plants expressing TIC4029 (encoded by SEQ ID NO:5) demonstrated efficacy against SBL and VBC, and suppression of SAW. Soybean plants expressing TIC4029 (encoded by SEQ ID NO:5) demonstrated efficacy against SBL, SFL, and VBC when tested in screenhouse trials in Brazil.

For expression in plant cells, the TIC4029 (SEQ ID NO:2), TIC4029_1 (SEQ ID NO:4), and TIC4029_8 (SEQ ID NO:10) proteins can be expressed to reside in the cytosol or targeted to various organelles of the plant cell. For example, targeting a protein to the chloroplast may result in increased levels of expressed protein in a transgenic plant while preventing off-phenotypes from occurring. Targeting may also result in an increase in pest resistance efficacy in the transgenic event. A target peptide or transit peptide is a short (3-70 amino acids long) peptide chain that directs the transport of a protein to a specific region in the cell, including the nucleus, mitochondria, endoplasmic reticulum (ER), chloroplast, apoplast, peroxisome and plasma membrane. Some target peptides are cleaved from the protein by signal peptidases after the proteins are transported. For targeting to the chloroplast, proteins contain transit peptides which are around 40-50 amino acids. For descriptions of the use of chloroplast transit peptides, see U.S. Pat. Nos. 5,188,642 and 5,728,925. Many chloroplast-localized proteins are expressed from nuclear genes as precursors and are targeted to the chloroplast by a chloroplast transit peptide (CTP). Examples of such isolated CTP's include, but are not limited to, those associated with the small subunit (SSU) of ribulose-1,5,-bisphosphate carboxylase, ferredoxin, ferredoxin oxidoreductase, the light-harvesting complex protein I and protein II, thioredoxin F, enolpyruvyl shikimate phosphate synthase (EPSPS), and transit peptides described in U.S. Pat. No. 7,193,133. It has been demonstrated in vivo and in vitro that non-chloroplast proteins may be targeted to the chloroplast by use of protein fusions with a heterologous CTP and that the CTP is sufficient to target a protein to the chloroplast. Incorporation of a suitable chloroplast transit peptide such as the Arabidopsis thaliana EPSPS CTP (CTP2) (see, Klee et al., Mol. Gen. Genet. 210:437-442, 1987) or the Petunia hybrida EPSPS CTP (CTP4) (see, della-Cioppa et al., Proc. Natl. Acad. Sci. USA 83:6873-6877, 1986) has been shown to target heterologous EPSPS protein sequences to chloroplasts in transgenic plants (see, U.S. Pat. Nos. 5,627,061; 5,633,435; and 5,312,910; and EP 0218571; EP 189707; EP 508909; and EP 924299). For targeting the TIC4029 or the truncation variant TIC4029 toxin protein to the chloroplast, a sequence encoding a chloroplast transit peptide is placed 5′ in operable linkage and in frame to a synthetic coding sequence encoding the TIC4029 or the truncation variant TIC4029 toxin protein that has been designed for expression in plant cells.

It is contemplated that additional toxin protein sequences related to TIC4029 can be created using the amino acid sequence of TIC4029 to create novel proteins with novel properties. The TIC4029 toxin proteins can be aligned to combine differences at the amino acid sequence level into novel amino acid sequence variants and making appropriate changes to the recombinant nucleic acid sequence encoding variants.

It is contemplated that improved variants of the TIC4029 protein toxin class can be engineered in planta by using various gene editing methods known in the art. Such technologies used for genome editing include, but are not limited to, ZFN (zinc-finger nuclease), meganucleases, TALEN (Transcription activator-like effector nucleases), and CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)/Cas (CRISPR-associated) systems. These genome editing methods can be used to alter the toxin protein coding sequence transformed within a plant cell to a different toxin coding sequence. Specifically, through these methods, one or more codons within the toxin coding sequence is altered to engineer a new protein amino acid sequence. Alternatively, a fragment within the coding sequence is replaced or deleted, or additional DNA fragments are inserted into the coding sequence, to engineer a new toxin coding sequence. The new coding sequence can encode a toxin protein with new properties such as increased activity or spectrum against insect pests, as well as provide activity against an insect pest species wherein resistance has developed against the original insect toxin protein. The plant cell comprising the gene edited toxin coding sequence can be used by methods known in the art to generate whole plants expressing the new toxin protein.

It is also contemplated that fragments of TIC4029 or protein variants thereof can be truncated forms wherein one or more amino acids are deleted from the N-terminal end, C-terminal end, the middle of the protein, or combinations thereof wherein the fragments and variants retain insect inhibitory activity. These fragments can be naturally occurring or synthetic variants of TIC4029 or derived protein variants but should retain the insect inhibitory activity of at least TIC4029. Examples of truncated variant proteins of TIC4029 include TIC4029_1 (SEQ ID NO:4) and TIC4029_8 (SEQ ID NO:10).

Proteins that resemble the TIC4029 proteins can be identified and compared to each other using various computer-based algorithms known in the art (see Table 1). Amino acid sequence identities reported in this application are a result of a Clustal W alignment using these default parameters: Weight matrix: blosum, Gap opening penalty: 10.0, Gap extension penalty: 0.05, Hydrophilic gaps: On, Hydrophilic residues: GPSNDQERK, Residue-specific gap penalties: On (Thompson, et al (1994) Nucleic Acids Research, 22:4673-4680). Percent amino acid identity is further calculated by the product of 100% multiplied by (amino acid identities/length of subject protein). Other alignment algorithms are also available in the art and provide results similar to those obtained using a Clustal W alignment and are contemplated herein.

It is intended that a protein exhibiting insect inhibitory activity against a Lepidopteran insect species is related to TIC4029 if the protein is used in a query, e.g., in a Clustal W alignment, and the proteins of the present invention as set forth as SEQ ID NO:2 are identified as hits in such alignment in which the query protein exhibits at least 87% to about 100% amino acid identity along the length of the query protein that is about 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 100%, or any fraction percentage in this range.

In addition to percent identity, TIC4029 and the truncation variants of TIC4029 can also be related by primary structure (conserved amino acid motifs), by length and by other characteristics. Characteristics of the TIC4029 protein toxins class are reported in Table 1.

As described further in the Examples of this application, synthetic nucleic acid molecule sequences encoding TIC4029, TIC4029_1, and TIC4029_8 were designed for use in plants, encoded respectively by SEQ ID NOs:5-7 (TIC4029), SEQ ID NO:8 (TIC4029_1), and SEQ ID NO:9 (TIC4029_8).

Expression cassettes and vectors containing a recombinant nucleic acid molecule sequence can be constructed and introduced into plants, in particular into corn, soybean or cotton plant cells in accordance with transformation methods and techniques known in the art. For example, Agrobacterium-mediated transformation is described in U.S. Patent Application Publications 2009/0138985A1 (soybean), 2008/0280361A1 (soybean), 2009/0142837A1 (corn), 2008/0282432 (cotton), 2008/0256667 (cotton), 2003/0110531 (wheat), 2001/0042257 A1 (sugar beet), U.S. Pat. No. 5,750,871 (canola), U.S. Pat. No. 7,026,528 (wheat), and U.S. Pat. No. 6,365,807 (rice), and in Arencibia et al. (1998) Transgenic Res. 7:213-222 (sugarcane) all of which are incorporated herein by reference in their entirety. Transformed cells can be regenerated into transformed plants that express TIC4029, TIC4029_1, and TIC4029-8 and demonstrate pesticidal activity through bioassays performed in the presence of Lepidopteran pest larvae using plant leaf disks obtained from the transformed plants. Plants can be derived from the plant cells by regeneration, seed, pollen, or meristem transformation techniques. Methods for transforming plants are known in the art.

As an alternative to traditional transformation methods, a DNA sequence, such as a transgene, expression cassette(s), etc., may be inserted or integrated into a specific site or locus within the genome of a plant or plant cell via site-directed integration. Recombinant DNA construct(s) and molecule(s) of this disclosure may thus include a donor template sequence comprising at least one transgene, expression cassette, or other DNA sequence for insertion into the genome of the plant or plant cell. Such donor template for site-directed integration may further include one or two homology arms flanking an insertion sequence (i.e., the sequence, transgene, cassette, etc., to be inserted into the plant genome). The recombinant DNA construct(s) of this disclosure may further comprise an expression cassette(s) encoding a site-specific nuclease and/or any associated protein(s) to carry out site-directed integration. These nuclease expressing cassette(s) may be present in the same molecule or vector as the donor template (in cis) or on a separate molecule or vector (in trans). Several methods for site-directed integration are known in the art involving different proteins (or complexes of proteins and/or guide RNA) that cut the genomic DNA to produce a double strand break (DSB) or nick at a desired genomic site or locus. Briefly as understood in the art, during the process of repairing the DSB or nick introduced by the nuclease enzyme, the donor template DNA may become integrated into the genome at the site of the DSB or nick. The presence of the homology arm(s) in the donor template may promote the adoption and targeting of the insertion sequence into the plant genome during the repair process through homologous recombination, although an insertion event may occur through non-homologous end joining (NHEJ). Examples of site-specific nucleases that may be used include zinc-finger nucleases, engineered or native meganucleases, TALE-endonucleases, and RNA-guided endonucleases (e.g., Cas9 or Cpf1). For methods using RNA-guided site-specific nucleases (e.g., Cas9 or Cpf1), the recombinant DNA construct(s) will also comprise a sequence encoding one or more guide RNAs to direct the nuclease to the desired site within the plant genome.

Recombinant nucleic acid molecule compositions that encode bacterial expressed TIC4029, TIC4029-1, and TIC4029-8, and the plant expressed TIC4029, TIC4029-1, and TIC4029_8 proteins can be expressed with recombinant DNA constructs in which a polynucleotide molecule with an ORF encoding the protein is operably linked to genetic expression elements such as a promoter and any other regulatory element necessary for expression in the system for which the construct is intended. Non-limiting examples include a plant-functional promoter operably linked to a TIC4029, TIC4029-1, or TIC4029_8 protein encoding sequence for expression of the protein in plants or a Bt-functional promoter operably linked to a TIC4029, TIC4029-1, or TIC4029_8 protein encoding sequence for expression of the protein in a Bt bacterium or other Bacillus species. Other elements can be operably linked to the TIC4029, TIC4029-1, or TIC4029_8 protein encoding sequence including, but not limited to, enhancers, introns, untranslated leaders, encoded protein immobilization tags (HIS-tag), translocation peptides (i.e., plastid transit peptides, signal peptides), polypeptide sequences for post-translational modifying enzymes, ribosomal binding sites, and RNAi target sites. Exemplary recombinant polynucleotide molecules provided herewith include, but are not limited to, a heterologous promoter operably linked to a polynucleotide such as SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, and SEQ ID NO:9 that encodes the respective polypeptides or proteins having the amino acid sequence as set forth in SEQ ID NO:2 (encoded by SEQ ID NO:1 and SEQ ID NOs:5-7), SEQ ID NO:4 (encoded by SEQ ID NO:3 and SEQ ID NO:8), and SEQ ID NO:10 (encoded by SEQ ID NO:9). A heterologous promoter can also be operably linked to synthetic DNA coding sequences encoding a plastid targeted TIC4029, TIC4029-1, or TIC4029-8. The codons of a recombinant nucleic acid molecule encoding for proteins disclosed herein can be substituted by synonymous codons (known in the art as a silent substitution).

A recombinant DNA construct comprising TIC4029, TIC4029-1, or TIC4029_8 protein encoding sequences can further comprise a region of DNA that encodes for one or more insect inhibitory agents which can be configured to concomitantly express or co-express with a DNA sequence encoding a TIC4029, TIC4029-1, or TIC4029_8 protein, an insect inhibitory dsRNA molecule, or an ancillary protein. Ancillary proteins include, but are not limited to, co-factors, enzymes, binding-partners, or other agents that function to aid in the effectiveness of an insect inhibitory agent, for example, by aiding its expression, influencing its stability in plants, optimizing free energy for oligomerization, augmenting its toxicity, and increasing its spectrum of activity. An ancillary protein may facilitate the uptake of one or more insect inhibitory agents, for example, or potentiate the toxic effects of the toxic agent.

A recombinant DNA construct can be assembled so that all proteins or dsRNA molecules are expressed from one promoter or each protein or dsRNA molecule is under separate promoter control or some combination thereof. The proteins of this invention can be expressed from a multi-gene expression system in which one or more proteins of TIC4029, TIC4029-1, or TIC4029_8 are expressed from a common nucleotide segment which also contains other open reading frames and promoters, depending on the type of expression system selected. For example, a bacterial multi-gene expression system can utilize a single promoter to drive expression of multiply-linked/tandem open reading frames from within a single operon (i.e., polycistronic expression). In another example, a plant multi-gene expression system can utilize multiply-unlinked or linked expression cassettes, each cassette expressing a different protein or other agent such as one or more dsRNA molecules.

Recombinant polynucleotides or recombinant DNA constructs comprising a TIC4029, TIC4029-1, or TIC4029_8 protein encoding sequence can be delivered to host cells by vectors, e.g., a plasmid, baculovirus, synthetic chromosome, virion, cosmid, phagemid, phage, or viral vector. Such vectors can be used to achieve stable or transient expression of a TIC4029, TIC4029_1, or TIC4029_8 protein encoding sequence in a host cell, or subsequent expression of the encoded polypeptide. An exogenous recombinant polynucleotide or recombinant DNA construct that comprises a TIC4029, TIC4029-1, or TIC4029_8 protein encoding sequence and that is introduced into a host cell is referred in this application as a “transgene”.

Transgenic bacteria, transgenic plant cells, transgenic plants, and transgenic plant parts that contain a recombinant polynucleotide that expresses any one or more of TIC4029, TIC4029-1, or TIC4029_8 or a related family toxin protein encoding sequence are provided herein. The term “bacterial cell” or “bacterium” can include, but is not limited to, an Agrobacterium, a Bacillus, an Escherichia, a Salmonella, a Pseudomonas, Brevibacillus, Klebsiella, Erwinia, or a Rhizobium cell. The term “plant cell” or “plant” can include but is not limited to a dicotyledonous or monocotyledonous plant. The term “plant cell” or “plant” can also include but is not limited to an alfalfa, banana, barley, bean, broccoli, cabbage, brassica, carrot, cassava, castor, cauliflower, celery, chickpea, Chinese cabbage, citrus, coconut, coffee, corn, clover, cotton, a cucurbit, cucumber, Douglas fir, eggplant, eucalyptus, flax, garlic, grape, hops, leek, lettuce, Loblolly pine, millets, melons, nut, oat, olive, onion, ornamental, palm, pasture grass, pea, peanut, pepper, pigeonpea, pine, potato, poplar, pumpkin, Radiata pine, radish, rapeseed, rice, rootstocks, rye, safflower, shrub, sorghum, Southern pine, soybean, spinach, squash, strawberry, sugar beet, sugarcane, sunflower, sweet corn, sweet gum, sweet potato, switchgrass, tea, tobacco, tomato, triticale, turf grass, watermelon, and wheat plant cell or plant. In certain embodiments, transgenic plants and transgenic plant parts regenerated from a transgenic plant cell are provided. In certain embodiments, the transgenic plants can be obtained from a transgenic seed, by cutting, snapping, grinding or otherwise disassociating the part from the plant. In certain embodiments, the plant part can be a seed, a boll, a leaf, a flower, a stem, a root, or any portion thereof, or a non-regenerable portion of a transgenic plant part. As used in this context, a “non-regenerable” portion of a transgenic plant part is a portion that cannot be induced to form a whole plant or that cannot be induced to form a whole plant that is capable of sexual and/or asexual reproduction. In certain embodiments, a non-regenerable portion of a plant part is a portion of a transgenic seed, boll, leaf, flower, stem, or root.

Methods of making transgenic plants that comprise insect, Lepidoptera-inhibitory amounts of a TIC4029, TIC4029_1, or TIC4029_8 protein are provided. Such plants can be made by introducing a recombinant polynucleotide that encodes any of the proteins provided in this application into a plant cell, and selecting a plant derived from said plant cell that expresses an insect, Lepidoptera-inhibitory amount of the protein. Plants can be derived from the plant cells by regeneration, seed, pollen, or meristem transformation techniques. Methods for transforming plants are known in the art.

Processed plant products, wherein the processed product comprises a detectable amount of a TIC4029, TIC4029-1, or TIC4029_8 protein, an insect inhibitory segment or fragment thereof, or any distinguishing portion thereof, are also disclosed herein. In certain embodiments, the processed product is selected from the group consisting of plant parts, plant biomass, oil, meal, sugar, animal feed, flour, flakes, bran, lint, hulls, processed seed, and seed. In certain embodiments, the processed product is non-regenerable. The plant product can comprise commodity or other products of commerce derived from a transgenic plant or transgenic plant part, where the commodity or other products can be tracked through commerce by detecting nucleotide segments or expressed RNA or proteins that encode or comprise distinguishing portions of a TIC4029, TIC4029_1, or TIC4029_8 protein.

Plants expressing the TIC4029, TIC4029_1, or TIC4029_8 proteins can be crossed by breeding with transgenic events expressing other toxin proteins and/or expressing other transgenic traits such as herbicide tolerance genes, genes conferring yield or stress tolerance traits, and the like, or such traits can be combined in a single stacked vector so that the traits are all linked.

As further described in the Examples, TIC4029, TIC4029_1, or TIC4029_8 protein-encoding sequences and sequences having a substantial percentage identity to TIC4029, TIC4029_1, or TIC4029-8, can be identified using methods known to those of ordinary skill in the art such as polymerase chain reaction (PCR), thermal amplification, and hybridization. For example, the proteins TIC4029, TIC4029-1, or TIC4029_8 can be used to produce antibodies that bind specifically to related proteins and can be used to screen for and to find other protein members that are closely related.

Furthermore, nucleotide sequences encoding the TIC4029, TIC4029_1, or TIC4029_8 toxin proteins can be used as probes and primers for screening to identify other members of the class using thermal-cycle or isothermal amplification and hybridization methods. For example, oligonucleotides derived from sequences as set forth in SEQ ID NOs:5-9 can be used to determine the presence or absence of a TIC4029, TIC4029_1, or TIC4029_8 transgene in a deoxyribonucleic acid sample derived from a commodity product. Given the sensitivity of certain nucleic acid detection methods that employ oligonucleotides, it is anticipated that oligonucleotides derived from sequences as set forth in SEQ ID NOs:5-9 can be used to detect a TIC4029, TIC4029_1, or TIC4029_8 transgene in commodity products derived from pooled sources where only a fraction of the commodity product is derived from a transgenic plant containing any of the transgenes. It is further recognized that such oligonucleotides may be used to introduce nucleotide sequence variation in each of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, and SEQ ID NO:9. Such “mutagenesis” oligonucleotides are useful for identification of TIC4029, TIC4029_1, and TIC4029_8 amino acid sequence variants exhibiting a range of insect inhibitory activity or varied expression in transgenic plant host cells.

Nucleotide sequence homologs, e.g., insecticidal proteins encoded by nucleotide sequences that hybridize to each or any of the sequences disclosed in this application under stringent hybridization conditions, are also an embodiment of the present invention. The invention also provides a method for detecting a first nucleotide sequence that hybridizes to a second nucleotide sequence, wherein the first nucleotide sequence (or its reverse complement sequence) encodes a pesticidal protein or pesticidal fragment thereof and hybridizes to the second nucleotide sequence. In such case, the second nucleotide sequence can be any of the nucleotide sequences presented as of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, or SEQ ID NO:9 under stringent hybridization conditions. Nucleotide coding sequences hybridize to one another under appropriate hybridization conditions, such as stringent hybridization conditions, and the proteins encoded by these nucleotide sequences cross react with antiserum raised against any one of the other proteins. Stringent hybridization conditions, as defined herein, comprise at least hybridization at 42° C. followed by two washes for five minutes each at room temperature with 2×SSC, 0.1% SDS, followed by two washes for thirty minutes each at 65° C. in 0.5×SSC, 0.1% SDS. Washes at even higher temperatures constitute even more stringent conditions, e.g., hybridization conditions of 68° C., followed by washing at 68° C., in 2×SSC containing 0.1% SDS.

One skilled in the art will recognize that, due to the redundancy of the genetic code, many other sequences are capable of encoding such related proteins, and those sequences, to the extent that they function to express pesticidal proteins either in Bacillus strains or in plant cells, are embodiments of the present invention, recognizing of course that many such redundant coding sequences will not hybridize under these conditions to the native Bacillus sequences encoding TIC4029, TIC4029-1, and TIC4029_8 variants. This application contemplates the use of these and other identification methods known to those of ordinary skill in the art, to identify TIC4029, TIC4029_1, and TIC4029_8 protein-encoding sequences and sequences having a substantial percentage identity to TIC4029, TIC4029-1, and TIC4029_8 protein-encoding sequences.

This disclosure also contemplates the use of molecular methods known in the art to engineer and clone commercially useful proteins comprising chimeras of proteins from pesticidal proteins; e.g., the chimeras may be assembled from segments of the TIC4029, TIC4029_1, or TIC4029_8 proteins to derive additional useful embodiments including assembly of segments of TIC4029, TIC4029_1, or TIC4029_8 proteins with segments of diverse proteins different from TIC4029, TIC4029_1, or TIC4029_8 proteins and related proteins. The TIC4029, TIC4029-1, or TIC4029_8 proteins may be subjected to alignment to each other and to other Bacillus, Paenibacillus or other pesticidal proteins (whether or not these are closely or distantly related phylogenetically), and segments of each such protein may be identified that are useful for substitution between the aligned proteins, resulting in the construction of chimeric proteins. Such chimeric proteins can be subjected to pest bioassay analysis and characterized for the presence or absence of increased bioactivity or expanded target pest spectrum compared to the parent proteins from which each such segment in the chimera has been derived. The pesticidal activity of the polypeptides may be further engineered for activity to a particular pest or to a broader spectrum of pests by swapping domains or segments with other proteins or by using directed evolution methods known in the art.

Methods of controlling insects, in particular Lepidoptera infestations of crop plants, with the TIC4029, TIC4029_1, or TIC4029_8 proteins are disclosed in this application. Such methods can comprise growing a plant comprising an insect- or Lepidoptera-inhibitory amount of a TIC4029, TIC4029_1, or TIC4029_8 toxin protein. In certain embodiments, such methods can further comprise any one or more of: (i) applying any composition comprising or encoding a TIC4029, TIC4029_1, or TIC4029_8 toxin protein to a plant or a seed that gives rise to a plant; and (ii) transforming a plant or a plant cell that gives rise to a plant with a polynucleotide encoding a TIC4029, TIC4029_1, or TIC4029_8 toxin protein. In general, it is contemplated that a TIC4029, TIC4029_1, or TIC4029_8 toxin protein can be provided in a composition, provided in a microorganism, or provided in a transgenic plant to confer insect inhibitory activity against Lepidopteran insects.

In certain embodiments, a recombinant nucleic acid molecule encoding TIC4029, TIC4029_1, or TIC4029_8 toxin proteins is the insecticidally active ingredient of an insect inhibitory composition prepared by culturing recombinant Bacillus or any other recombinant bacterial cell transformed to express a TIC4029, TIC4029_1, or TIC4029_8 toxin protein under conditions suitable to express the TIC4029, TIC4029_1, or TIC4029_8 toxin protein. Such a composition can be prepared by desiccation, lyophilization, homogenization, extraction, filtration, centrifugation, sedimentation, or concentration of a culture of such recombinant cells expressing/producing said recombinant polypeptide. Such a process can result in a Bacillus or other entomopathogenic bacterial cell extract, cell suspension, cell homogenate, cell lysate, cell supernatant, cell filtrate, or cell pellet. By obtaining the recombinant polypeptides so produced, a composition that includes the recombinant polypeptides can include bacterial cells, bacterial spores, and parasporal inclusion bodies and can be formulated for various uses, including as agricultural insect inhibitory spray products or as insect inhibitory formulations in diet bioassays.

In one embodiment, to reduce the likelihood of resistance development, an insect inhibitory composition comprising TIC4029, TIC4029_1, or TIC4029_8 protein can further comprise at least one additional polypeptide that exhibits insect inhibitory activity against the same Lepidopteran insect species, but which is different from the TIC4029, TIC4029_1, or TIC4029_8 toxin protein. Possible additional polypeptides for such a composition include an insect inhibitory protein and an insect inhibitory dsRNA molecule. One example for the use of such ribonucleotide sequences to control insect pests is described in Baum, et al. (U.S. Patent Publication 2006/0021087 A1).

In other embodiments, such composition/formulation can further comprise at least one additional polypeptide that exhibits insect inhibitory activity to an insect that is not inhibited by an otherwise insect inhibitory protein of the present invention to expand the spectrum of insect inhibition obtained. For example, for the control of Hemipteran pests, combinations of insect inhibitory proteins of the present invention can be used with Hemipteran-active proteins such as TIC1415 (US Patent Publication 2013-0097735 A1), TIC807 (U.S. Pat.

Additional polypeptides for the control of Coleopteran, Lepidopteran, and Hemipteran insect pests, which can be combined with the insect inhibitory proteins of the TIC4029 family, can be found on the Bacillus thuringiensis toxin nomenclature website maintained by Neil Crickmore (on the world wide web at btnomenclature.info). Broadly, it is contemplated that any insect inhibitory protein known to those of skill in the art can be used in combination with the proteins of the TIC4029 family both in planta (combined through breeding or molecular stacking) or in a composition or formulation as a biopesticide or combination of biopesticides.

The possibility for insects to develop resistance to certain insecticides or insecticidal proteins has been documented in the art. One insect resistance management strategy is to employ transgenic crops that express two distinct insect inhibitory agents that operate through different modes of action. Therefore, any insects with resistance to either one of the insect inhibitory agents can be controlled by the other insect inhibitory agent. Another insect resistance management strategy employs the use of plants that are not protected to the targeted Lepidopteran pest species to provide a refuge for such unprotected plants. One particular example is described in U.S. Pat. No. 6,551,962, which is incorporated by reference in its entirety.

Other embodiments such as topically applied pesticidal chemistries that are designed for controlling pests that are also controlled by the proteins disclosed herein to be used with proteins in seed treatments, spray on, drip on, or wipe on formulations can be applied directly to the soil (a soil drench), applied to growing plants expressing the proteins disclosed herein, or formulated to be applied to seed containing one or more transgenes encoding one or more of the proteins disclosed. Such formulations for use in seed treatments can be applied with various stickers and tackifiers known in the art. Such formulations can contain pesticides that are synergistic in mode of action with the proteins disclosed, so that the formulation pesticides act through a different mode of action to control the same or similar pests that can be controlled by the proteins disclosed, or that such pesticides act to control pests within a broader host range or plant pest species that are not effectively controlled by the TIC4029, TIC4029_1, and TIC4029-8 pesticidal proteins.

The aforementioned composition/formulation can further comprise an agriculturally-acceptable carrier, such as a bait, a powder, dust, pellet, granule, spray, emulsion, a colloidal suspension, an aqueous solution, a Bacillus spore/crystal preparation, a seed treatment, a recombinant plant cell/plant tissue/seed/plant transformed to express one or more of the proteins, or bacterium transformed to express one or more of the proteins. Depending on the level of insect inhibitory or insecticidal inhibition inherent in the recombinant polypeptide and the level of formulation to be applied to a plant or diet assay, the composition/formulation can include various by weight amounts of the recombinant polypeptide, e.g. from 0.0001% to 0.001% to 0.01% to 1% to 99% by weight of the recombinant polypeptide.

In view of the foregoing, those of skill in the art should appreciate that changes can be made in the specific aspects which are disclosed and still obtain a like or similar result without departing from the spirit and scope of the invention. Thus, specific structural and functional details disclosed herein are not to be interpreted as limiting. It should be understood that the entire disclosure of each reference cited herein is incorporated within the disclosure of this application.

EXAMPLES Example 1 Discovery, Cloning, and Expression of TIC4029 and the TIC4029 Variants TIC4029_1 and TIC4029_8

A sequence encoding a novel Bacillus thuringiensis pesticidal protein was identified, cloned, sequence confirmed, and tested in insect bioassay. The pesticidal protein, TIC4029 was isolated from Bt species EGBS0016 and represents a novel Cry1Ca-related protein. Bt strain EGBS0016 was initially identified as a spore forming, crystal and plasmid containing strain of Bt or Bt-like bacteria. DNA was isolated from EGBS0016 and sequenced. The assembled sequence was then analyzed bioinformatically. The TIC4029 protein was identified by pfam analysis to hits of endotoxin domains and identity to known Cry1Ca toxins. The full length TIC4029 protein amino acid sequence exhibits 86% identity to TIC1425 (U.S. Pat. No. 10,626,151. The insect toxin TIC1425 demonstrated activity against Cotton leaf worm (Alabama argillacea), European corn borer (Ostrinia nubilalis), Fall armyworm (Spodoptera frugiperda), Sugarcane borer (Diatraea saccharalis), and Southwestern corn borer (Diatraea grandiosella). Polymerase chain reaction (PCR) primers were designed to amplify a full-length copy of the coding region for TIC4029 from total genomic DNA isolated from the Bt species EGBS0016. The PCR amplicon also included the translational initiation and termination codons of the coding sequence.

The TIC4029 coding sequence was cloned using methods known in the art into a Bt expression vector in operable linkage with a Bt expressible promoter. Spore and soluble protein preparations were used in bioassay.

In addition, two truncated variants of TIC4029 were produced, TIC4029_1 and TIC4029-8. TIC4029_1 comprises a deletion of the protoxin domain and consists of amino acids 1-603 relative to TIC4029 (see FIGS. 1a-1b ). The coding sequence of TIC4029_1 was synthesized and cloned into a bacterial expression vector in operable linkage with a Bt expressible promoter. Spore and soluble protein preparations were used in bioassay.

TIC4029_8 comprises deletions of the N-terminal amino acid segment and protoxin domain of TIC4029 and consists of amino acids 28-607 of TIC4029 (see FIGS. 1a-1b ). In addition, an ATG codon was then introduced, replacing the arginine residue of TIC4029 at amino acid position 27 to enable translation initiation of the TIC4029_8 protein. The TIC4029_8 amino acid sequence represents the tryptic core of TIC4029. A sequence encoding TIC4029_8 was tested in planta for activity as described in Examples 4 and 5.

Example 2 TIC4029 and TIC4029_1 Exhibit Lepidopteran Toxic Activity in Insect Bioassay

The pesticidal proteins TIC4029 and TIC4029_1 were expressed in Bt and assayed for toxicity to various species of Lepidoptera. TIC4029 was also assayed for toxicity to various species of Coleoptera, Hemiptera, and Diptera.

TIC4029 was assayed for toxicity to the Lepidopteran insect species Black cutworm (BCW, Agrotis ipsilon), Corn earworm (CEW, Helicoverpa zea, also known as Soybean podworm), European corn borer (ECB, Ostrinia nubilalis), Fall armyworm (FAW, Spodoptera frugiperda), Southern armyworm (SAW, Spodoptera eridania), Soybean looper (SBL, Chrysodeixis includens), Southwestern corn borer (SWC, Diatraea grandiosella), Sugarcane borer (SCB, Diatraea saccharalis), Sunflower looper (SFL, Rachiplusia nu), Tobacco budworm (TBW, Heliothis virescens), and Velvet bean caterpillar (VBC, Anticarsia gemmatalis); the Coleopteran species Colorado potato beetle (CPB, Leptinotarsa decemlineata) and Western Corn Rootworm (WCR, Diabrotica virgifera); the Hemipteran species Neotropical Brown Stink Bug (NBSB, Euschistus heros) and Western tarnished plant bug (WTP, Lygus hesperus); and the Dipteran species Yellow Fever Mosquito (YFM, Aedes aegypti). Bioassay using microbial host cell-derived protein samples containing TIC4029 exhibited activity against the Lepidopteran species BCW, CEW, ECB, FAW, SAW, SBL, SWC, SCB, SFL, TBW, and VBC. Activity was also observed against the Dipteran species YFM.

The bacterial encoded TIC4029_1 exhibited toxic activity against SBL and VBC. In addition, TIC4029 and TIC4029_1 exhibited toxic activity against Black armyworm (BAW, Spodoptera cosmioides).

Example 3 Synthetic Sequences Encoding TIC4029, TIC4029_1, or TIC4029_8 for Plant Expression

Synthetic coding sequences were designed to encode TIC4029, TIC4029_1 or TIC4029_8 for expression of each of these toxins in plants.

The synthetic sequences were synthesized, according to methods generally described in U.S. Pat. 5,500,365, to avoid certain inimical problem sequences such as ATTTA and A/T rich plant polyadenylation sequences while substantially preserving the amino acid sequence of the native protein. TIC4029_PL-1 (SEQ ID NO:5), TIC4029_PL-2 (SEQ ID NO:6), and TIC4029_PL-3 (SEQ ID NO:7) each are different coding sequence constructs encoding TIC4029. One synthetic coding sequence was designed for TIC4029_1 (SEQ ID NO:8) and one synthetic coding sequence was designed for TIC4029_8 (SEQ ID NO:9).

These were transferred into plant transformation vectors using skills known in the art. The transformation vectors used to transform soybean plants comprised a first transgene cassette for expression of the applicable pesticidal protein including a plant functional constitutive promoter in operable linkage to a leader, the toxin coding sequence, an untranslated region (UTR), and a plant functional transcription termination and polyadenylation sequence. A second transgene cassette expressing a selectable marker, in this case spectinomycin resistance, was also included in the vector. The transformation vectors used to transform corn plants included a first transgene cassette for expression of the applicable pesticidal protein and included a plant functional constitutive promoter in operable linkage to a leader sequence, an intron sequence, an untranslated region (UTR) including a transcription and translation termination sequence and a plant polyadenylation sequence and included a second transgene cassette encoding glyphosate tolerance for selection of transformed plant cells.

Example 4 TIC4029, TIC4029_1, and TIC4029_8 Demonstrate Lepidopteran Toxic Activity in Stably Transformed Soybean Plants

Binary plant transformation vectors comprising transgene cassettes designed to express the pesticidal proteins TIC4029, TIC4029_1, and TIC4029_8 were constructed using methods known in the art. The resulting vectors were used to stably transform soybean plants with expression cassettes encoding these toxin proteins. Plant tissues expressing these toxin proteins were used in insect bioassay against various Lepidopteran insect species as described herein.

Soybean plant cells were transformed with the binary transformation vectors using an Agrobacterium-mediated transformation method. The transformed cells were induced to form plants by methods known in the art. Bioassays using plant leaf disks obtained from the transformed plants were performed similar to methods described in U.S. Pat. No. 8,344,207. A single freshly hatched neonate larvae less than one day old was placed on each leaf disc sample and allowed to feed for approximately four days. A non-transformed soybean plant was used as a negative control. Multiple R₀ single-copy insertion events arising from each binary vector were assessed against Southern armyworm (SAW, Spodoptera eridania), Soybean looper (SBL, Chrysodeixis includens), Soybean pod worm (SPW, Helicoverpa zea), and Velvet bean caterpillar (VBC, Anticarsia gemmatalis). An efficacy rating score (efficacy score) which ranged from 0 to 3 was assigned to each event based upon the percent leaf damage in the bioassay for each event and the percentage of events that shared the lowest percent range of damage (Penetrance) as shown in Table 2. A rating score of 3 represents the most efficacious effect of toxicity based on feeding on that particular sample. A rating score of 2 represents that the sample on which the larvae was feeding exhibited suppression of growth, molting, or caused morbidity and often, mortality.

TABLE 2 Standards for Efficacy rating score, Leaf Damage Percentage, and Penetrance for Soybean Plants Expressing Toxin. Efficacy score Percent Leaf Damage Penetrance 0 >50% ≥80% 1 <50% ≥20% 2 <30% ≥20% 3 ≤10%  ≥50% Table 3 illustrates the efficacy scores for R₀ soybean plants expressing TIC4029, TIC4029_1, and TIC4029_8. The numbers in parenthesis represent the number of events that shared the lowest percent range of damage/total number of events assayed, and “NT” indicates not tested.

As can be seen in Table 3, R₀ 9 of the 10 constructs used to express TIC4029 in stably transformed soybean were efficacious against SBL. All 9 constructs used to express TIC4029_1 and both constructs used to express TIC4029_8 in stably transformed soybean were efficacious against SBL. Four of the constructs used to express TIC4029PL-1 were efficacious against SAW, while 4 other constructs provided suppression of SAW.

Selected R₀ soybean plants expressing TIC4029, TIC4029_1, and TIC4029_8 were allowed to self-pollinate and produce R₁ seed. The R₁ seed was used to grow R₁ plants. R₁ plants homozygous for the pesticidal protein expression cassette were selected for leaf disc bioassay against SAW, SBL, SPW and VBC. Table 4 shows the efficacy rating scores for R₁ homozygous plants expressing TIC4029, TIC4029_1, and TIC4029_8.

As can be seen in Table 4, R₁ homozygous plants derived from 5 selected constructs expressing TIC4029 were efficacious against SBL. R₁ homozygous plants derived from 8 selected constructs expressing TIC4029 were efficacious against SAW. R₁ homozygous plants derived from 8 selected constructs expressing TIC4029_1 and 1 selected construct expressing TIC4029_8 were efficacious against SAW.

In one trial, R₁ homozygous plants derived from transformation with Construct-1 and Construct-3 expressing TIC4029 were assayed using leaf disc assays as described above against Bean shoot moth (Crocidosema aporema), resulting in 50% to 100% mortality. TIC4029 is active against Bean shoot moth (Crocidosema aporema). R₁ homozygous plants derived from transformation with Construct-3 expressing TIC4029 were assayed against Cry1Ac-resistant Sunflower looper (SFL, Rachiplusia nu) and were highly efficacious against Cry1Ac-resistant SFL.

Example 5 TIC4029, TIC4029_1, and TIC4029_8 Demonstrate Activity Against Southwestern Corn Borer in Stably Transformed Corn Plants

Binary plant transformation vectors comprising transgene cassettes designed to express the TIC4029, TIC4029_1, and TIC4029_8 pesticidal proteins were cloned using methods known in the art. The resulting vectors were used to stably transform corn plants. Tissues were harvested from the transformants and used in insect bioassay against various Lepidopteran insect species.

Corn plants were transformed with the binary transformation vectors as described in Example 3 using an Agrobacterium-mediated transformation method. The transformed cells were induced to form plants by methods known in the art. Bioassays using plant leaf disks were performed analogous to those described in U.S. Pat. No. 8,344,207. A single freshly hatched neonate larvae less than one day old was placed on each leaf disc sample and allowed to feed for approximately four days. A non-transformed corn plant was used to obtain tissue to be used as a negative control. Multiple transformation R₀ single-copy insertion events from each binary vector were assessed against Southwestern corn borer (SWC, Diatraea grandiosella). An efficacy rating score which ranged from 0 to 3 was assigned to each event based upon the percent leaf damage in the bioassay for each event and the percent events that shared the lowest percent range of damage (Penetrance) as shown in Table 2 of Example 3.

Table 5 below shows the efficacy scores for R₀ stably transformed corn plants expressing TIC4029, TIC4029_1, and TIC4029_8. The numbers in parenthesis represent the number of events that shared the lowest percent range of damage/total number of events assayed. For TIC4029, two constructs were used to transform plants, each comprising different coding sequences encoding TIC4029, but identical expression elements.

As can be seen in Table 5, R₀ single-copy corn plants expressing TIC4029 transformed with Construct-2 which comprised the TIC4029 coding sequence, TIC4029-2 (SEQ ID NO:6) and TIC4029_1 and TIC4029_8 were efficacious against SWC. Expression levels of TIC4029 from the coding sequence TIC4029PL-1 were much lower than the expression levels observed for TIC4029PL-2 which were likely responsible for the lower efficacy scores derived from constructs comprising the TIC4029PL-1 coding sequence. A selected R₀ single-copy plant transformed with Construct-2 expressing TIC4029 using the coding sequence, TIC4029PL-2 was allowed crossed with a non-transformed elite variety of corn. Heterozygous F₁ events derived from this cross were assayed against SWC. These heterozygous F₁ events were efficacious against SWC.

Example 6 TIC4029 is Efficacious Against Soybean Looper, Sunflower Looper, and Velvet Bean Caterpillar and Provides Suppression of Southern Armyworm in Screenhouse Trials

Soybean plants expressing TIC4029 were assayed for protection against selected insect pest species in screenhouse trials in the United States and in Argentina.

In the United States during the 2019 growth season, soybean plants expressing TIC4029 were assayed in screenhouse trials against Southern armyworm (SAW, Spodoptera eridania), Soybean looper (SBL, Chrysodeixis includens), Soybean podworm (SPW, Helicoverpa zea,), and Velvet bean caterpillar (VBC, Anticarsia gemmatalis) in several locations. Screenhouse trials were conducted in Jerseyville, Ill. against SAW and SBL, in Union City, Tenn. against SBL, and against VBC and SPW in Waterman, Ill. The events were evaluated using a randomized complete clock design. Each event plot was planted in a single six (6) foot row with approximately eight (8) seeds per foot. Each event had three (3) reps; hence each event was represented in the screenhouse by three (3) separate plots, randomly located within the screenhouse. A non-transformed event served as a negative control whose plots were also randomly assigned to locations within the screenhouse.

Infestation of SPW and VBC was accomplished using adult moths. The insects were reared to pupae in an insectary at Union City, Tenn. in adult emergence cages, and maintained in climate-controlled incubators. The insects were shipped to Waterman and Jerseyville, Ill. for release in the screenhouse. Approximately one thousand two hundred (1,200) to two thousand (2,000) adults were used for each release in the screenhouses. For SPW, adults were released in the screenhouse each week from the R1 to R2 stage of soybean development. With respect to VBC, adults were released in the screenhouse bi-weekly between the developmental stages of V4 to R3. Approximately one thousand two hundred (1,200) to two thousand (2,000) adults were released each time in the screenhouses. Adult moths required continuous access to a ten percent (10%) sucrose solution for normal longevity and fecundity. Plastic food containers were filled with absorbent cotton and then the sugar solution was poured into the container to completely saturate the cotton. The sugar solution was replenished daily until adult activity subsided which was usually around two weeks after the final release of adults.

For SAW infestation, a. direct egg infestation was used since this insect does not oviposit preferentially or uniformly on soybean. Approximately two hundred fifty thousand (250,000) to three hundred twenty thousand (320,000) eggs were used for each infestation, and applied bi-weekly from R1 to R3 stage of development. Pieces of paper containing equal numbers of SAW eggs were attached to plants by folding the paper over a sturdy leaf petiole in the upper canopy and stapling the paper together securely. One (1) paper was placed on a plant within one (1) foot of the front end of the plot, a second paper was placed on a plant in the middle of the plot, and a third paper was placed on a plant within one (1) foot of the back end of the plot.

The percent defoliation was assessed at different stages of plant development. For SAW, percent defoliation was assessed at R2.8, R4.1, R4.8, and R6.0 developmental stage at Jerseyville, IL. For SBL, percent defoliation was determined at R2.0, R3.1, R4.2, and R5.5 developmental stage at Union City, Tenn., and at R5.4 and R5.8 developmental stage at Jerseyville, Ill. For VBC, percent defoliation was assessed at R3.9, R5.0, and R5.4 developmental stage at Waterman, Ill. For SPW, percent defoliation was assessed at R4.1, R4.7, R5.4, and R5.8 developmental stage at Waterman, Ill. A maximum percent defoliation was derived from the highest percent defoliation observed amongst the different developmental stages for each insect. Table 6 below shows the average maximum percent defoliation for plants expressing TIC4029 for SAW, SBL, and VBC. The average maximum percent defoliation for SPW was similar to the negative control and is not presented in Table 6.

TABLE 6 Average maximum percent defoliation for soybean plants expressing TIC4029 in United States screenhouse trials. SAW SBL VBC Location Neg TIC4029 Neg TIC4029 Neg TIC4029 Jerseyville, IL 56.5 12.5 25.0 0.0 Union City, TN 71.5 0.2 Waterman, IL 50.3 0.8

As can be seen in Table 6, plants expressing TIC4029 were efficacious in controlling SBL and VBC; and demonstrated suppression of SAW.

Screenhouse trials were also conducted at two locations in Argentina, Fran Luis, BA and Pergamino, BA during the 2019-2020 growing season for soybean plants expressing TIC4029. Screenhouse trials were conducted in a similar manner as those in the United States in 2017. Each plot in the screenhouse comprised a row of forty-two (42) seeds in a two (2) meter row. Each event was represented by three (3) representative samples randomly located within the screenhouse. Screenhouse trials were conducted against the lepidopteran insect pests, Soybean looper (SBL, Chrysodeixis includens), Velvet bean caterpillar (VBC, Anticarsia gemmatalis), South American podworm (SAPW, Helicoverpa gelotopoeon), Sunflower looper (SFL, Rachiplusia nu), and Black armyworm (BAW, Spodoptera cosmioides).

The percent defoliation was assessed at different stages of plant development. For SBL, percent defoliation was assessed at R5.0, R5.5, and R6.0 developmental stage at Fran Luis, BA and at R4.0, R5.1, and R5.6 developmental stage at Pergamino, BA. For VBC, percent defoliation was assessed at R5.5, R6.0, and R6.5 developmental stage at Fran Luis, BA and at R5.0, R5.6, and R6.0 developmental stage at Pergamino, BA. For SFL, percent defoliation was assessed at R5.0, R5.3, R5.5, and R6.0 developmental stage at Fran Luis, BA and at R3.0, R4.0, R5.2, and R6.2 developmental stage at Pergamino, BA. For SAPW, percent defoliation was assessed at R4.4, R5.1, R5.5, and R6.0 developmental stage at Fran Luis, BA and at R3.0, R4.0, R5.1, and R6.2 developmental stage at Pergamino, BA. For BAW, percent defoliation was assessed at R3.0, R5.0, R5.5, and R6.0 developmental stage at Fran Luis, BA and at R5.1, R5.4, and R6.0 developmental stage at Pergamino, BA. A maximum percent defoliation was determined as described previously in this Example for each of the insect pests in each location. Table 7 below shows the average maximum percent defoliation for plants expressing TIC4029. The maximum percent defoliation for SAPW and BAW were equal to the controls and are not included in Table 7.

As can be seen in Table 7, soybean plants expressing TIC4029 were efficacious against SBL, VBC, and SFL.

TIC4029 is efficacious against SBL, VBC, and SFL; and provides suppression of SAW.
